Hi sorry to hear you are having so many problems. I think a lot of how you feel depends on your consultant. I had my hip replaced 2 years ago
when i was 50. My scar is lovely and not very noticeable, my health centre said it was a good looking scar only a week after op.
I am very pleased I had it done and I was completely pain free in the hip almost immediately. This was important to me as I have a lot of pain probs with my ankles which they cannpot do anything about. My consultant was young and very open to new ideas and even on the morning of the op he phone usa for some advice regarding the best type of replacemnet to use as I have osteoporosis. What may be of interest to you is one of the other patients was having her 4th replacement and she actually was in hospital for a couple of days less than me.
You must make your own mind up but I think it is good to live without pain, a much better quality of life. And the new replacements are lasting longer, especially in RA patients who may not be so active.
I dont know if any of this has been of any help but I hope so.
Take care
Love melanie
